ASRock published and then swiftly removed product pages for an AMD Radeon RX 9050 equipped with 4GB of GDDR6 VRAM on July 28, 2026, the same day the cardmaker officially launched an 8GB variant of the same GPU. The 4GB listing was first spotted by X user RubyRapids and reported by Digital Foundry before ASRock pulled the pages. The Verge

The 8GB model, formally designated the ASRock Radeon RX 9050 Challenger 8GB (model RX9050 CL 8G), carries full specifications on ASRock's product page. It features a boost clock of up to 2,600 MHz, a game clock of 1,920 MHz, 8GB of GDDR6 on a 128-bit memory bus running at 18 Gbps, 16 compute units, and 32 MB of cache. ASRock recommends a 450W power supply for the card. ASRock

The deleted 4GB listing, captured before removal, described a card built on AMD's RDNA 4 architecture with a 64-bit memory interface, 16 compute units, and a boost clock of up to 2,600 MHz at 18 Gbps. Halving the VRAM and narrowing the bus from 128-bit to 64-bit cuts memory bandwidth roughly in half compared to the 8GB model, while the compute unit count and boost clock remain identical.

AMD's own product page lists only the 8GB configuration of the Radeon RX 9050, with no 4GB variant appearing in AMD's official specifications. The company released Adrenalin Edition 26.7.1 on July 28, 2026, adding official driver support for the RX 9050, and the card appears as a selectable product on AMD's driver download page. AMD AMD

Tom's Hardware separately identified the 4GB RX 9050 in a Best Buy listing for a CyberPowerPC prebuilt gaming PC priced at $889. That system pairs the 4GB card with an AMD Ryzen 5 5500 CPU, 8GB of DDR4 RAM, and a 500GB SSD. Tom's Hardware VideoCardz

ASRock had not announced pricing for the 4GB RX 9050 at the time of the original reports, and ASRock and AMD did not immediately respond to The Verge's request for comment. The absence of the 4GB variant from AMD's own product page, combined with ASRock deleting the listings, leaves the card's official status unclear. The Verge

The broader context here is that 4GB of VRAM at a discrete GPU's launch in 2026 is a genuinely aggressive memory target. Modern game engines routinely allocate texture pools and frame buffers that exceed 4GB at 1080p with medium-to-high settings, and titles leveraging DirectX 12 Ultimate features such as mesh shaders and sampler feedback can push VRAM requirements well beyond that threshold. A 64-bit memory bus on top of a 4GB frame buffer compounds the constraint: effective bandwidth on the 4GB card would be roughly half that of the 8GB model's 128-bit implementation, assuming identical GDDR6 speeds.

The CyberPowerPC system at Best Buy sharpens the practical question. An $889 prebuilt with a Ryzen 5 5500 (a Zen 3 part launched in 2021), 8GB of DDR4, a 500GB SSD, and a 4GB RX 9050 is a configuration where every component sits at or near the floor of current-generation viability. The GPU is the component most likely to bottleneck first in any title released in the last two to three years.

Digital Foundry's reporting framed the 4GB listing against a worsening flash memory supply situation driven by AI demand. Whether that supply pressure is the direct cause of a 4GB RX 9050 variant, or whether AMD and its board partners are simply targeting the lowest possible price band in the budget segment, is not yet distinguishable from the available information.

What is verifiable: ASRock listed a 4GB RX 9050, pulled it, AMD's own pages show only the 8GB version, and a $889 prebuilt with the 4GB card is already surfacing at retail. The gap between a partner's listing and the GPU vendor's own product page is the detail worth tracking. If AMD confirms the 4GB variant, the RX 9050 becomes the lowest-VRAM discrete card launched on RDNA 4. If the listing was premature or an error, the 8GB model stands alone. Either outcome tells you something about where the budget GPU floor now sits.
